The Stein z'of the vulve /vf extemls axially in 'the cylinder b, passage (l, :mtl elntniller e, andr is provide-.il with :i piston i' in the vlinder b, as well ith the volvo in the elm m ber c. The distiiiiee helneen the 'vulve l'r :intl the piston r .is snelt that when the vulve /t' is on sont the piston f' is :it the further eml ol the Cylinder therefrom. Through this ont! ol` the cylinder is nnule n threaded perforation .u for the, engagement of :i snmll pipe for the admission ol' nir oi' steiim. 'lhis perl'oi'itt ion s is Inzidein the center of the einl olI the. euvlinder, intli zotetl, so that when :tir or sten m tidinitte'd through the pipe. t it nill properly octnitto the pieton, nnovininr it to the other entl thereof.
